COMPASS ATTACHMENT FOR PENCILS.

SPECIFICATION forming part of Letters Patent No. 375,257, dated December 20, 1887.

. To all whom it may concern.- J

Be it known that I, CLAES WM. BOMAN, of the city, county, and State of New York, have invented a certain new and useful Improvement in Compass Attachments for Pencils, of which the following is a specification.

In the compassattachment for pencils which I have devised the two legs are hinged to gether,as usual in compasses or dividers. One ofthe legsthe one which receives the pencil--is at its outer'end fashioned like a pencilholder-that is to say, is of tubular form and fitted to receive and hold a lead-pencil, and

above this pencil holder portion the leg is made trough-like, or is therwise cut away,so as to permit the other leg to be folded into this cutaway or trough-like portion, so that when the two legs are folded together they together will constitute, in effect, a prolongation of the pencil tube or holder, which prolongation will have the same orv approximately the same diameter as the pencil-tube, and will thus form a handle which will permit the device to be used with facility as apencil. The leg which folds into the other I prefer to make an extension-leg, so that when unfolded for use, as one leg of a compass, it may be extended to equal in length the pencil-carrying leg, and so that when no longer in use it may be contracted in length in order that it may fit into or against the cutaway portion (above the pencil-holding tube) of its fellow leg.

The nature of my improvement will be readily understood by reference to the accompanying drawings.

Figure l is a view of the device with the legs folded up, the whole being in condition to be used as a pencil. Fig. 2 is a view of the device with the legs unfolded and the extension-leg in readiness for use.

The device is preferably made of sheet metal. The two legs are hinged together at :0. One of the legs, which for convenience sake I term the pencilleg, consists at its outer end of a pencil receiving tube, A. Above this tubeA the leg is made trough-like, or is otherwise cut away or reduced, as at B, in order to permit the other leg to fold up properly.

'The pencil-holding tube A may be of any known and approved pattern. The parti- Application filed October 25, 1887. Serial No. 253,290. (No model.)

cular one shown in the drawings is constructed on the plan set forth in Letters Patent No. 368,517, of August 16,1887, the openings a permitting the point of the pencil P to be by hand projected beyond the tube, as shown in full lines in Fig. l, or to be drawn back into the tube, as shown in dotted lines in the same figure. The pencil-leg shown in the drawings, in fact, is a full tube throughout the part A and a half-tube, or nearly so, throughout the remainderB of its length, and this construction I prefer.

The cylindrical extension-leg O is of sufficiently less diameter than the other leg to fit snugly into the trough-like portion B when folded up, as in Fig. 1; but, for the same-reason, its length is not greater than that of the part B. In order to give it when unfolded a length equal to that of the pencil-leg, I provide it with an extension-piece, D, pointed at its outer end. This extension-piece is preferably made sliding and is conveniently combined with the leg 0 by making the latter tubular, as shown, and arranging the extension-piece D to slide therein. The piece can be moved and held in place by any suitable known means. One simple way is that shown in the drawingsviz., to make the leg at its upper end for a portion of its length to fit snugly in the outer tubular leg, O, to form a longitudinal slot, 7), in said leg 0, terminating at its lower end in a cross-sl0t, a, similar to that of a bayonet-catch, and to secure in the extension-piece a pin which projects through the slot and has on its outer end a button or knob, d, by which the extension-piece Dean be readily manipulated. A tip, 0, on leg 0 beyond the hinge-point, forms a convenient handle by which the leg can be worked.

Having described my improvement and the best way now known to me of carrying the same into effect, what I claim herein as new and of my own invention is- 1. The compass attachment for pencils, consisting of a pencil-leg having apencil-holding portion, A, and a trough-like or cutaway portion, B, and an extensionleg hinged to the pencil and arranged and adapted to fold up into the cut-away portion B, as and for the purposes hereinbefore set forth.
